CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 516,123, dated March 6, 1894. Application filed February 20, 1893- Serial No: 463,140 (No model.)

To all whom it may concern:

Be it known that we, ENGELBERT WILHELM Sonrurz, of Annenstrasse 4:8, and JoHAnNEs WALLMANN, of Oranienstrasse, 173, Berlin, in the Empire of Germany, have invented a new and useful Improvement in Self-Acting Couplings Disengaging from the Side for Railway-Carriages; and we do hereby declare that the following is a full, clear, and exact description of the invention.

Figure l is a face viewof the main-part A. Fig. 2 is a face view of the main-part B. Fig.

' 3: is a face view of the engaged coupling. Fig.

4 is a view of the inclined plane e.

While the many new railway-couplin gs are highly complicated and therefore very expensive the coupling described hereinafter isso simple as to be easily applied to any railwaycarriage whatever.

It consists of two main-parts A and B, which are fixed alternately to the front-walls of the carriages, Part A has a piece a to which piece Z) turning round I is fixed. This piece b now carries the two flanges d d and in front the inclined plane 0 with fine cheeks f f. Around gturns leverrlwith weight 70 and binding-piece It. Part B has a piece n to which piece 13 is fixed turning around m. This piece carries parts (1, binding-piecer and pressingpiece 3. The carriages being advanced toward one another, parts q and 4' will slide on the inclined plane 6 between the flanges d d and will then press lever 'i upward passing through below it until it is thrown back by pieces. The lever thus pulling back, piece It will come to lie on r and the coupling is engaged; the greater the force of drawing asunder, the tighter block 'r will press between h and b.

In order to disengage the coupling one need only reverse the lever i from the side of the carriage which can be easily done since the fulcrum is at the beginning of piece h. In order to compensate the difference of height between charged carriages and empty ones, the springs cand 0 have been contrived which will yield and thus bring about acorrect sliding in of the coupling-parts A and B.

Having thus described our invention, what We do claim as new, and desire to secure by Letters Patent, is

1. In a car coupling, the part B provided with the block r in combination with the part A having the plane I), and the flanges d, d, in which is pivoted weighted lever 1; having thereon the binding piece It, all substantially as described.

2. In a car coupling the hinged part B having parts q, '1' and s, in combination with the hinged part A, havingthe incline e and cheeks ff, and pivoted lever 71 and the springs c and 0, all substantially as described.
